Awareness of medical students about vitamin D deficiency at Ahfad University for women, Sudan.

Vitamin D deficiency is not only associated with rickets and osteomalacia, but also with several chronic diseases, such as cancer, ischaemic heart disease, and type 1and 2 diabetes mellitus. Worldwide, an estimated one billion people suffer from vitamin D deficiency. The prevalence of this problem is unknown in Sudan due to scarcity of research in this particular area of concern. The present study aimed to assess the awareness of vitamin D deficiency through the knowledge of the importance of vitamin D, the link to diseases, vitamin D resources and the importance of dietary supplements, in addition to assessing the sun exposure habits in a sample of female Sudanese medical students. It is a descriptive cross-sectional community-based study, conducted at Ahfad University for Women, Omdurman, Sudan. More than half (56 %) of the participants were aged 21-25 years and 30% were in the second academic class. The majority of the participants were aware of the importance of vitamin D; however, the awareness of relating it to the chronic diseases was poor. Overall, 61.9% declared that vitamin D supplementation is important, and sun exposure habits were good (64.5% didn't use sunblock and 87.6% get exposed for more than 10 minutes/day). There was significant association between the age categories and exposure to the sun without sunblock on a daily basis ( value = 0.007).
